Kβ/Kα intensity ratios for rare earth compounds using radioisotope induced X-ray fluorescence

Abstract

Measurements of the Kβ to Kα intensity yield for the rare earth elements in various chemical compounds and as the pure elements have been made utilising radioisotope induced fluorescence and a hyperpure germanium (HpGe) detection system. Deviations from the ratios anticipated from theoretical considerations or from existing compilations have been found for LaB₆, Ce(NH₄)₂(NO₃)₆, Pr₆O₁₁, Gd (citrate solution), Gd (EDTA solution), Tb₄O₇, Lu₂O₃, Lu (foil) and Eu in acid solution.
